MUS I C LEAF TURNER Filed Oct. 26, 1958 2 Sheets-Sheet 2 INVENTCR ATTO RN EYS Patented Nov. 19, 1940 UNITED STATES PATENT OFFICE 3 Claims.

l My invention relates to the handling of sheet music, and has among itsobjects and advantages the provision of an improved music leaf turner.

An object of my invention is to provide a music leaf turner embodyingnovel means for quickly and accurately turning thel pages of the sheetmusic in such a manner as to eliminate the necessity for having to takethe individual sheets between the fingers for turning purposes. Theturner embodies novel means for handling sheet music of different sizesand is so constructed as to effectively turn individual sheets or pagesof a book. The turning mechanism is incorporated in a frame structurewhich may be folded back upon the sheets or bound volume in the mannerof abook cover so as to provide a compact unit for handling purposes inaddition to affording protection for the music.

In the accompanying drawings:

In the embodiment Selected to illustrate my invention, Figure 1illustrates the music turner open for supporting the sheet music. Theframe units I0 are identical'in construction, each comprising side barsI2 and I4, end cross bars I6 and I8, and intermediate cross bars 20. Allthe cross bars I6, I8 and 20 have their ends arranged in overlappingrelation with the side bars I2 and I4 and are iixedly related thereto,as by rivets 22. A latch bar 24 is associated with each oi the framesI0, and each Latch bar is arranged in parallel relation with itsrespective side bars I2 and I4, centrally of its respective frame. Latchbars 24 are riveted to the end bars I6 and I8, as at 26.

Referring to Figures l and 2, the side bars I4 are hingedly connectedwith a center column 28,

(Cl. Sli-486) so that the frames Ill may be folded to the position ofFigure 6, at which time the frames and the columns deiine a congurationsimulating the covers of a book, for housing the sheet musictherebetween.

Column 28 comprises a metal strap 30 of a length slightly longer thanthe side bars I4. Spacers 32 extend longitudinally oi the bottom face ofthe strap 30 for supporting a second strap 34 in spaced relation withthe strap 30. Straps 3U vand 34 and the spacer 32 are connected intounitary structure by screws 36.

Hinges 38 are attached to the side bars I4 and the strap 36 by screws40. The axes of the hinges 38 are located directly over the meeting linebetween the side bars I4 and the edges of the strap 30; Figure 2illustrates the frames I0 opened, at which time the adjoining edges ofthe side bars I4 have abutting relation with the edges of the strap 38to support the frames I0 in a common plane with the strap 30.

Between the spacers 32 and the straps 30 and 34, I mount al plurality ofwires 42 which are curved at their lower ends, as at 44, to providegrips facilitating rotation of the wires. The upper ends of the wires 42are provided with right angular arms 46 of lengths substantially equalto the Width of one frame I0. The right angular arms 46 are doubled backupon themselves at 48 to provide right angular extensions which stackone upon the other when arranged according to Figure 1. Similarly, theouter ends of the arms 46 are bent to provide cross extensions 50 whichalso stack one upon the other. Extensions 48 and 50 constitute abutmentswhich cooperate with each other for preventing the arms 46 from assuminga disorderly arrangement should the arms 46 be offset or shiftedslightly laterally of one another.

Upon each arm 46 I mount a pair of V-shaped links 52 each having itsends looped at 54 about its respective arm 46. To the bight of each link52 is connected a conventional spring clip 56. Each arm 46 carries twolinks 52 so that each sheet of music connected with one of the arms 46will have two clip connections. The links 52 are slidably related totheir respective arms 46 so that the clips 56 may be adjusted to sheetsor pages of variable sizes. One sheet is connected with each of the arms46.

In operation, the sheets are connected with the arms 46, and lie on theright hand frame Il] when viewing Figure 1. The sheets are turned overfrom the right hand frame I0 onto the left hand frame I0. In cases wherethe music is in book form, the book is positioned with its backpositioned along the column 28. The slidable connection between thelinks 52 and their respective arms 46 permit effective turning of boundsheets even though the bound volume is not accurately aligned with thecenter column 28.

In use, the frames I are positioned substantially in an uprightposition, as indicated by the angularity of the center column 28 inFigure 5. The weight of bound volumes may be supported on a rest 58,extending transversely of the frames, see Figure 1. Rest 58 comprisesstraps 69 lying flat upon the latch bars 24 and transversely of thesame. Straps 60 are provided with right angular flanges 62 which carrythe weight of the music. The inner ends of the straps 60 are connectedwith a plate 64, through the medium of hinges 66 having their axesaligned with the axes of the hinges 38. Plate 64 is provided with aright angular flange 68 and the plate is slidable freely relatively tothe center column 28.

Each latch bar 24 is provided with a plurality of closely spacedperforations 10, and each flange 62 is provided with a pin 12 arrangedto project through selected perforations in its respective latch bar topermit the rest 58 to be latched in different positions of adjustmentlongitudinally of the latch bars 24 so as to accommodate music ofdifferent lengths. Each strap 60 is provided with a loop 14 whichextends underneath its respective latch bar 24 for holding the rest 58in assembled relation with the latch bar. Loops 14 are loosely relatedto the latch bars 24 so as to permit the rest 58 to be elevatedsufficiently far to bring the pins 12 out of holding relation with theperforations 10. Thus the rest 58 may easily be moved upwardly ordownwardly of the frames I0.

In Figures 2, 5 and 6, I illustrate the strap 34 of the center column 28as being provided with a loop 16 into which the end 18 of a standard 80may be detachably inserted. End 18 is bent at an angle to the standardso as to hold the center column 28 in the angular position of Figure 5,with the standard 80 positioned substantially vertically. The lower endof the standard 80 is provided with an end 82 shaped for removableinsertion in a loop 84 fixedly related to a supporting bar 86.

The ends of the bar 86 are positioned inside the U-bend 88 of clampparts 90. Each clamp part 90 carries a screw 92 extending through a slot94 in a companion clamp bar 96 having a hook 98. Companion clamp bar 96includes an angular reach |00 having a threaded opening |02 for thereception of an adjusting screw |04 extending loosely through an opening|06 in the fiange |08 of the clamp part 90. Screw |04 includes a flangeI0 bearing against the flange |08 and is provided with a knurled knob||2 to facilitate turning. Hooks 98 cooperate with the U-bends 80 to theend that the parts might be clamped to a supporting structure (notshown.)

Latch bars 24 have their ends curved upwardly, at I4 when viewingFigure 1. The latch bars 24 extend beyond the cross bar I6 so as toafford rests for the arms 46 in either position. Standard 80 isdetachably connected with the center column 28 as well as with the bar86. At the same time, the bar 86 is detachably connected with theU-bends 88. Thus the parts may be disconnected for packaging purposes soas to provide a compact arrangement facilitating transportation andmovement from place to place.

Figure 6 illustrates the manner in which the device may be folded in themanner of a book. A U-shaped clip ||6 is arranged to be pressed over theside bars |2 for holding the frames l0 in the position of Figure 6 withthe sheet music or book clamped between the frames I0. With the devicefolded according to Figure 6, the reaches of the latch bars 24 extendingbeyond the cross bars |6 and I8 afford protection for the frames I0 andthe music associated therewith when the device is placed in a containeror package. Wires 44, while being centrally housed in the manner ofFigure 2, rotate easily, while the grips 44 provide effective means forselectively turning the wires, which in turn turns the sheets ||6connected with the clip 58. Rest 58 folds with the .frames ||J so as tobe housed inside the frames.

Without further elaboration, the foregoing will so fully illustrate myinvention that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service.
